Virus shuts down factories of major iPhone component manufacturer TSMC

Apple touts the cybersecurity of its iPhone, but less can be said for the exclusive manufacturer who makes the processor for the iPhone.

Semiconductor foundry TSMC, or Taiwan Semiconductor Manufacturing Company, was hit by a virus late Friday night, which forced it to shut down several factories according to Debbie Wu at Bloomberg. The virus and the shutdown were confirmed by TSMC representatives.

It is not clear at this time which factories were hit, or whether those factories were producing the iPhone’s main processor. Apple is expected to unveil new iPhones this fall, and supply chain disruptions in the critical month of August could have significant adverse consequences for the rapid availability of the new phone before the key Christmas holiday.

TSMC has grown to become the largest independent semiconductor foundry in the world, with profits last year of $11.6 billion. The company has benefitted from partnerships with smartphone companies like Apple, which produces the designs for its own A-series chips and then contracts out their manufacturing to foundries.

Alongside Foxconn, TSMC is one of Taiwan’s most important and profitable companies, and is an obvious target both due to its wealth and scale, as well as its centrality in the increasingly fraught cross-straight relations between China and Taiwan. China has made becoming the world leader in semiconductors a national priority, and companies like TSMC are deeply competitive with mainland foundries.

That’s the paranoid context for many tech executives in Taiwan, and while the culprit of this particular virus is not yet publicly known, eyes and fingers are already beginning to point in one direction.

More information about the attack is expected to be available next week.
